Kory Boyd, Randall Hild, and Aage Giessing were snowmobiling in Wasatch County backcountry when a massive snow storm approached. They quickly realized they needed to get moving.

As the snow came in and day shifted to night Thursday, the men tried to make it to safety on their own, but the situation quickly became dangerous. After hours of being trapped in the snow and enduring bitterly cold temperatures the men began to show early signs of frostbite. Eventually they found shelter under some trees and built a fire. There was no cell phone service and little food. But the men did have something that would ultimately save their lives – a SPOT Satellite Tracker, thrown into a pack at the last minute.

Two Canadian hikers were found on Mt. Lafayette after one of them activated his SPOT Satellite GPS Messenger. New Hampshire Fish and Game Department officials rescued the two hikers, after they ran into severe conditions on the mountain. "The only information that led us to starting the search was that we had this personal locator beacon signal activated," said Capt. John Wimsatt. "Otherwise, we wouldn't be searching."

John Chepulis, 65, is in critical condition after an injury caused him 10 broken bones and a punctured lung. Fortunately for John his friends had a SPOT Satellite GPS MessengerTM . Once the SPOT’s emergency alert was activated a helicopter arrived at the GPS coordinates air lifted John to safety.

Cora Edmunds' husband, son and nephew were stranded at sea near Makkovik just before dark on Friday, when the motor on their boat broke down.With strong winds driving the craft away further out, rowing to shore was not an option.But a situation that could have ended tragically had a positive outcome instead, thanks to a satellite tracking device called a "SPOT." The device traces users' coordinates and relays them by computer, enabling people elsewhere to log on and see where they are.The men pressed the SOS button on the device, alerting Cora Edmunds, as well as the agency that handles the calls.
